What?? This is a ridiculous conspiracy.
MK Ultra was real, yes.
But to suggest anyone who uses: butterflies, feline imagery, mirrors, chessboards, pink/purple or any colour of the rainbow (basically any colour that exists at all) is a mind controlled MK Ultra slave, is ridiculous.
And there is no evidence that any of these singers were actually programmed by the CIA. They were abused yes. But not everything is a CIA plot.
You've gone too far down the rabbit hole my friend. Not everything is as simple as "blame the CIA".
